47 : 30
وَلَوۡ نَشَآءُ لَأَرَيۡنَٰكَهُمۡ فَلَعَرَفۡتَهُم بِسِيمَٰهُمۡۚ وَلَتَعۡرِفَنَّهُمۡ فِي لَحۡنِ ٱلۡقَوۡلِۚ وَٱللَّهُ يَعۡلَمُ أَعۡمَٰلَكُمۡ
If We willed, We could show them to you [O Prophet], so you would recognize them by their faces, but you will surely recognize them by the manner of their speech. And Allah knows all what you do.
